Improvement in vehicle axle boxes and journals



UNITED STATES PATENT oaron JAMES A. MANNING, OF DANVILLE, INDIANA.

IMPROVEMENT IN VEHICLE AXLE BOXES AND JOURNALS.

- Specification forming part of Letters Patent N 0. 217,698, dated July22, 1879 application filed December 3, 1878.

To all whom it may concern:

Be it known that I, JAMES A. MANNING, of Danville, in the county ofHendricks and State of Indiana, have invented a new and ImprovedAxle-Box and Journal, of which the following is a specification.

My invention relates to an improved form of axle-box and journal forvehicles, whereby rattling is prevented, the box may be adjusted tocompensate for wear, the journal will retain the oil or grease, and thebox is prevented from wedging upon the journal.

The invention will first be described in connection with the drawings,and then pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal section of myimproved axlebox and journal. Fig. 2 is a cross-section at the line 2020. Fig. 3 is a cross-section at the line as a; and Fig. 4 is across-section of the journal at the line 3 3 Similar letters ofreference indicate corresponding parts.

a represents one end of a carriage or other axle. The inner end of thejournal is formed with a tapering or conical enlargement, b. The largerpart of said cone, next to the axle a, -is formed as a flange or collar,0, and is threaded to receive a screw-collar, d, that may be adjustedupon the flange 0, and is held from turning by a screw-pin, e, thatpasses from the outside of the collar d into any one of the notches f ofthe flange 0. (See Fig. 2.)

g is the metal box, that is held in the hub (not shown) by radial lugsh. The inner endof the box g is formed to set snugly upon the conicalenlargement b of the journal. I prefer to form the surface of thecone 1) slightly concave, as shown, and the box 9 convex to correspond,which formation acts to preven t the box wedging upon the journal. Theend of box g sets against a leather-washer, 2', that is between the boxand the screw-collar (I. Wear is compensated for by setting up thecollar cl, as before described; and the collar d also prevents the box 9from jamming upon the journal. The outer end of the box 9 is madeflaring to fit upon a conical sleeve, k, that is held upon the outer endof the journal by a nut, l, as hereinafter described. The surface ofsleeve k is concave and the box convex to correspond, for the samepurpose as mentioned in connection with the cone 1).

The conical sleeve is is connected atits outer and large end to acollar, m, the connection being made by an exterior thread on the collarm and an interior thread in the sleeve k. The projecting edge of thecollar at has a flange, n, and the nut l a rim or flange, 0, that isturned over the flange n of the collar, whereby the nut and flange areconnected; but the nut I may turn independentof the sleeve is and collarm.

The nut lscrews upon the thread 12, that is formed on the outer end ofthe journal, as usual. The sleeve is is prevented from turning by ashort rib, q projecting at the inside of the sleeve, which enters eitherone of the longitudinal grooves 1; cut in the surface of the journal.(See Fig; 1.) The sleeve 10 may be adjusted lengthwise by turning thecollar 122. To facilitate the said adjustment I provide a hole, 8, inflange 0 of nut Z, and form a groove, it, inside the collar on, so thatby inserting a nail or similar instrument through the hole 8 into groovet the collar 122 may be turned.

I The surface of the sleeve 70, at its larger end, is screw-threaded toreceive a screw-collar, u, that is similar to the collar 01 at the innerend of the journal, and answers a similar purpose. o is a washer betweenthe collar a and end of box g. Thecollar is kept from turning upon thesleeve by a screw pin, 12, that passes through the collar a, through aslot, u, in sleeve 70, and into a groove, o in surface of collar m. Thescrew-pin o therefore prevents movement upon each other of the collar m,sleeve 70, and collar a. The said pin o is to be removed when the partsare to be adjusted.

w and y are recesses formed at the inside of box 9 to serve asgrease-receptacles. They may be connected by a spiral groove, as shownby dotted lines in Fig. 1. The recess y is contiguous to the inner endof conical sleeve 70, and prevents the end of the sleeve from wearing orembedding itself in the box, which it might do if the recess 3 were notprovided.

By the construction above described there can be no rattling of the boxand journal, the lubricating material is retained upon the contactsurfaces, and the box prevented from wedging upon the journal by theshape of the journal and the collars at each end of the box. The partsmay be also readily adjusted and wear compensated for.

In applying my invention to an old spindle I make use of a conicalsleeve, to take theplace of the conical enlargement at the inner end ofthe spindle. It will be kept in place by a tongue on the inside, in thesame manner as the front cone.

Having thus described my invention, what I claim as new, and, desire tosecure by Letters Patent, is-

1. The combination, with a journal having concave cone .h at one end andconcave sleevecone k at the other, of the correspondinglyconstructed box9, the collars d a m, screws 0 v, and washers 'i v, as and 'for thepurpose specified.

2. The combination and arrangement of the collar m and nut l with thesleeve k, substantially as and for the purpose as set forth.

JAMES A. MANNING.
